[Asterisk-Users] the pstn line is noisy, busydetect can detect hangup?
I have a X101P connected to my analog PBX. I can?t detect hangups on this line While the line is connected to the PBX, I can never detect busy and the line hangs at the end of every call. busydetect Alg. compares silence with tone .the pstn line is noisy. can it work? how improve busydetect alg? how filter noise in dsp.c?
